Explanation: Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen. The atomic emission is powered by energetic radiation from the hot young stars, whose powerful winds and radiation also sculpt and erode the denser pillar shapes. Stars could still be forming inside the pillars by gravitational collapse. This field spans around 40 light-years at the estimated distance of NGC 7822.Credit: NASA, APOD.
